METAL THRESHOLD AND WEATHER-STRIP. I

SPECIFICATION forming part of Letters Patent No. 580,801, dated April13, 1897. Application filed August 15, 1896. Serial No. 602,909. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMEs T. RAMsDEN, a citizen of the United States,residing at Cherokee, in the county of Cherokee and State of Iowa, haveinvented a certain new, useful, and valuable Improvement in MetallicThresholds and YVeather-Strips, of which the following is a full, clear,and exact description.

My invention has relation to metallic thresholds and weather-stripsadapted to be applied to doors; and it consists in the novelconstruction and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a combined metallic thresholdand door-strip which when the door is closed will efiectually close thecrack between the lower edge of the door and the threshold.

The further object of the invention is to provide such a device thatwill not interfere with the opening or closing of the door.

The further object of the invention is to provide such a device which isautomatic in its operation.

In the accompanying drawings, Figure 1 is a perspective view of thelower part of a door, doorframe, and threshold, showing theWeather-strip attached to the door. Fig. 2 is a transverse sectionalview of the lower part of the door and the sill, showing the positionsassumed by the parts when the door is partly opened. Fig. 3 is atransverse sectional view of the lower part of the door, showing theposition of the parts when the door is closed. Fig. 4 is a perspectiveview of the lower part of the door with the covering-strip of theweather-strip removed. Fig. 5 is a perspective viewof a shield or hoodused at the end of the weather-strip. Fig. 6 is asectional view of theshield or hood.

The door is provided near its lower edge and on its outside with ahorizontal plate 1, said plate being secured to the door by any suitablemeans. The weather-strip consists of the metallic part 2, said parthaving the major portion of its upper edge 3 curved to the front andhaving the intermediate flat section 4. At its lower edge the said partis bent under, as at 5. The upper part of the Weather-strip 2 isprovided with the elongated perforations 6 6. Said perforations arelocated in the hollow of the curve formed by the junction of thesections 3 and 4 of the strip. The nails or screws 7 pass through saidperforations, and also pass through suitable perforations in the plate 1and enter the door. The weather-strip 2 is loosely mounted on said nailsor screws 7, and thereby the said strip is permitted to have a certainamount of hinge play, as indicated by the different positions of thestrip, as shown in Figs. 2 and 3. The elongated perforations 6 preventany lateral movement of the said strip. At any convenient point theupper edge of the strip 2 is provided with a section 8, which is not inthe same plane as the sec tion 3. A fiat spring 9 is secured to thedoor, and the lower part of said spring comes in contact with the edgeof the section 8. Said spring when the door is open is adapted to bringthe upper edge of the section 8 as near as possible to the door, andthereby the outer edge 5 of the strip 2 is raised and disengages thethreshold, as shown in Fig. 2. The plate 10 is secured to the door abovethe strip 2. Said plate extends out from the door, and at its lower.edge is provided with an inwardlyextending flange 11. When the door isclosed, the section 3 of the strip 2 is adapted to come in contact withthe flange 11, as shown in Fig. 3. The spring 9 and the end of the plate10 is covered by the hood 11, as shown in Fig. 1. The said hood, inaddition to protecting the spring and the plate, prevents anything fromcatching in the end of the plate 10.

The threshold consists of the metallic strip 2, supported from beneathby the block 13. The outer edge of the threshold is inclined downward,as at 14, and when the weatherstrip 2 is in the position as shown inFig. 3 the section 5 comes down against the downwardly-extending surface14 of the threshold, thereby making a tight joint and preventing the airor moisture from getting in between the lower edge of the door and theupper surface of the threshold. On the side of the door-frame and alittle above the threshold is secured the elongated perforated lug 15.Said lug is secured in place by means of the screw 16. The said lug isadapted to be shifted horizontally and secured in its proper position bytightening the screw 16. When the parts are in the position shown inFig. 2 and the door is closed, the inner edge of the lug 15 comes incontact with the section 5 of the strip 2 and forces the same downaround the outer edge of the threshold, and when the door is shut thesaid lug 15 will have forced the parts in the position shown in Fig. 3.

When the door is open, the spring 9, bearing against the section 8 ofthe strip 2, will force the outer end of the strip up, and as the dooris opened the said end of the said strip will clear the threshold, andthe door can be opened without interference.

When the door is closed, as shown in Fig. 3, it will be seen that theweather-strip is against the lower outer face and edge of the door, andthus there is no space left between the inner face of the strip and theouter face of the door to admit the passage of air behind the strip. Itwill also be seen that when the door is closed its outer face is insubstantially the same perpendicular line as the outer edge of thethreshold, and thus a good cover can be made by the weather-strip overthe crack between the lower edge of the door and the threshold.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In combination with a door, a threshold having at its outer edge aretreating surface, the outer edge of the threshold being in the sameperpendicular line as the outer face of the door when the door isclosed, a weatherstrip hinged to the outer face of the door, the innerface of the weather-strip adapted to come in contact with the lower edgeof the outer face of the door when the door is closed, saidweather-strip having at its lower edge a retreating section, saidretreating section of the strip adapted to come in contact with theretreating surface of the threshold when the door is closed and closethe crack at the bottom of the door.

2. In combination with a door having a weather-strip hinged thereon, athreshold consisting of a metallic strip having an elevated section, aretreating section formed. in the strip at the outer edge of thethreshold, the weather-strip on the door adapted to engage theretreating section of the threshold when the door is closed.
